The modeling lamps can be set to full brightness, set so that their output is proportional to the flashpower
adjustment, or turned off. Additionally, the lamps can be set to indicate the unit's recycle status by going
dark when the unit is fired and returning to previous brightness when recycle is complete.
Model Lamp ON (white): This button turns the eight modeling lamps on - the lamps are collectively
adjusted or turned all off or all on, depending on the position of the "TRACK" switch (described below).
Model Lamp TRACK (dark grey): When depressed, the modeling lamps will track the flashpower settings.
When released, the lamps will remain at full brightness regardless of changes made in the flashpower.
Model Lamp CYCLE (light grey): When depressed, the modeling lamps will visually indicate the recycle
status by going dark when the unit is flashed, then coming back on when the unit is recycled. When
re-leased, the lamps remain on during recycle. This recycle indication feature may be used whenever the
lamps are on, whether the lamps are set to full or tracking mode.
Remote Control Jack
The standard Paul C. Buff™ remote control jack accepts wired or wireless remote control of flashpower,
modeling lamp output and triggering. Plugging the provided phone cord of any Paul C. Buff™ remote
control into the jack causes the unit's flashpower and modeling to be externally controlled. When a cord
is plugged in, the rear panel controls are ignored - signals will be received from the remote. Plugging in a
remote control does not, however, defeat the slave eye.

1 second to Full Power (propor tionately faster at reduced power settings)
1/2000 second at Full Power
the flash duration becomes somewhat longer as the power is reduced, as with all competitive
variable flashpower systems, reaching approx. 1/1200 second at the minimum power setting
5.6 volts (low current - safe for digital cameras)
120 VAC, 50 – 60 Hz, 6 Amp Circuit Breaker
a set of eight 10-Watt, 24-Volt bulbs
500 to 3,000 hour lifespan; total output comparable to a conventional 150 Watt lamp
(approx. 2,200 Lumens)
two half-circle 6-inch diameter tubes (10mm)
250,000 to 1,000,000 flash lifespan
5500K at Mid-Power
varies +/- 200º at other power levels – typical of studio flash units with variable power
